When outfitted with its
trench digging package, The Alpine Magnum is perfectly suited for
digging trenches for sprinkler system installation, cable laying,
and edging around concrete sidewalks and lawn
fixtures.

The
secret to the Magnum's performance in trench digging is speed -
utilizing it's rapid 4800 rpm cutting head, the Magnum is capable
of digging a 20 inch deep trench. Another advantage to the
Magnum for trench digging applications is its portability. The
Magnum can get in and around nearly any work environment, and with
its highly versatile stand, the Magnum is easy to control and move.

Sprinkler System
Installation:

The Magnum is
especially suited for installing sprinkler systems because of its
high rpm engine and the ease and maneuverability of use. When
installing sprinkler systems, you don't want to have to rely
on a bulky, cumbersome four wheeled machine that might not
even give enough clearance to put sprinkler lines near the
house, or patio. The Magnum will make a trench about
2.5 inches wide by 10 inches deep just by pulling
the machine backwards with the transport wheel set mounted
on the machine.
It will trench about 300 lineal feet an hour
when using in this manner.

The Magnum's trenches are
great for sprinkler systems because it's easy to use, light weight,
and can fit into the back of a pickup for transportation.
Additionally, it's easy to control trench depth, negotiate corners
and use on uneven land surfaces.

Unlike
rototillers or other
commonly used ground-breaking machines, the Magnum cuts easily
through most small roots and clay. This can save a lot of time,
especially in work environments with shallow topsoil.
